Using Docker with Azure Functions and SignalR Service
Requirements
Azure Account (https://azure.microsoft.com/en-us/free/)
Docker
Tezos Node with enabled RPC endpoint supporting following calls
/monitor/heads/main
/chains/main/blocks/hash
In this configuration we are using a different docker image - this one is only sending a new blocks to our Azure Function, which then sends parsed information to subscribers through Azure SignalR Service.
If you just want to use a Docker container without having to setup Azure infrastructure please check Using Docker documentation section.
Ready-to-use docker image is available from Docker Hub here: https://hub.docker.com/repository/docker/tezoslive/agileventurestezpusherconsoleapp
Example of the docker run command
setting the
Tezos:NodeUrlenv. variable to https://172.17.0.1:8732setting the
Azure:AzureFunctionUrlenv. variable to https://myfunction.azurewebsites.netsetting the
Azure:AzureFunctionKeyenv. variable to MySecretFunctionKey
Be sure to configure the following ENV keys correctly per your environment
Tezos:NodeUrlAzure:AzureFunctionUrlAzure:AzureFunctionKey
docker run -it --env Tezos:NodeUrl="https://172.17.0.1:8732" \--env Azure:AzureFunctionUrl="https://myfunction.azurewebsites.net" \--env Azure:AzureFunctionKey="MySecretFunctionKey" \tezoslive/agileventurestezpusherconsoleapp
This infrastructure setup has the following benefits
It allows you to have a more robust security out of the box as all communication is encrypted by TLS.
It makes scaling your applications for thousands of subscribers much easier by using serveless compute with scalable SignalR Service.
